La Statistique envahit pratiquement tous les domaines d'application, aucun n'en est exclus; elle permet d'explorer et d'analyser des corpus de données de furthermore en plus volumineux : l'ère des big facts et du information mining s'ouvre à nous ! Cette omniprésence s'accompagne bien souvent de l'absence de regard critique tant sur l'origine des données que sur la manière de les traiter. La facilité d'utilisation des logiciels de traitement statistique permet de fournir quasi instantanément des graphiques et des résultats numériques. Le risque est donc grand d'une acceptation aveugle des conclusions qui découlent de son emploi, comme uncomplicated citoyen ou comme homme politique.
